The Association of Unaided Central Board of Secondary Education (CBSE) schools in Nagaland opposed CBSE’s mandate to implement the Three-Language Formula under the National Education Policy (NEP) 2020.
Nagaland has 17 major tribal languages and no single common regional language, while English is the official language and medium of instruction.
The state faces a shortage of trained teachers, textbooks, and a standard curriculum for implementing multiple languages.
The Three-Language Formula was first recommended by the Kothari Commission (1964–66) and adopted in the National Policy on Education (1968).
NEP 2020 allows students to study three languages with flexibility, but CBSE requires at least two Indian languages up to Class 10.
By census and mathematical measures (like the Herfindahl-Hirschmann Index), Nagaland ranks as the most linguistically diverse state.
It is home to at least 14 recognized languages and 17 dialects spoken by its major tribes.
